With the development of the socio-economy and the continuous improvement of people's living standards, consumer attitudes have evolved, placing greater emphasis on quality of life and living environments. Yak down is obtained from yaks living at altitudes above 3,500 meters. The unique frigid climate endows yak down with characteristics such as a smooth and soft handfeel, excellent elasticity, superior moisture absorption and release, high resistance to abrasion and pilling, and strong fiber durability. Premium yak down has an average fineness of 19 micrometers, making it an ideal high-end apparel fabric. Compared to cashmere, it offers better abrasion and pilling resistance while maintaining a clear price advantage.
Cashmere, known for its excellent elasticity, softness, and warmth, has long been favored by consumers. However, cashmere fiber production is limited by ecological factors, making it difficult to meet growing demand. Additionally, its high cost makes pure cashmere spinning economically challenging. Moreover, pure cashmere yarn has relatively low strength, especially when using short cashmere fibers, which not only complicates spinning but also affects fabric performance.
After dechroming, yak down closely resembles cashmere in appearance and properties, with no significant difference in handfeel. Given its lower raw material cost compared to cashmere, blending dechromed yak down with cashmere to produce mixed yarns holds vast market potential.
To address this, this patent presents an interlaced and entangled plied yarn, comprising a first yarn, a second yarn, and a third yarn. The first and second yarns are mutually entangled, while the third yarn alternately passes through adjacent entanglement points between them, achieving a three-way ply structure. This design results in a compact yarn body with uniform yet varied fancy effects while allowing functional customization based on requirements.
